Chronic pancreatitis (CP) is an inflammatory disorder characterized by inflammation and fibrosis, resulting in a progressive and irreversible destruction of exocrine and endocrine pancreatic tissue. Clinicians should attempt to classify patients into one of the six etiologic groups according to the TIGARO classification system. MRI/MRCP, if possible with
secretin
enhancement, is considered the imaging modality of choice for the diagnosis of early-stage disease.In CP, pain is the most disabling symptom, with a significant impact on quality of life. Pain should be assessed using the Izbicki score and preferably treated using the "pain ladder" approach. In painful CP, endoscopic therapy (ET) can be considered as early as possible. This procedure can be combined with extracorporeal shock-wave lithotripsy (ESWL) in the presence of large (> 4 mm), obstructive stone(s) in the pancreatic head, and with ductal stenting in the presence of a single main pancreatic duct (MPD) stricture in the pancreatic head with a markedly dilated MPD. Pancreatic stenting should be pursued for at least 12 months in patients with persistent pain relief. On-demand stent exchange should be the preferred strategy. The simultaneous placement of multiple, side-by-side, pancreatic stents can be recommended in patients with MPD strictures persisting after 12 months of single plastic stenting. We recommend surgery in the following cases: a) technical failure of ET ; b) early (6 to 8 weeks) clinical failure ; c) definitive biliary drainage at a later time point; d) pancreatic ductal drainage when repetitive ET is considered unsuitable for young patients; e) resection of an inflammatory pancreatic head when pancreatic cancer cannot be ruled out; f) duodenal obstruction. Duodenopancreatectomy or oncological distal pancreatectomy should be considered for patients with suspected malignancy. Pediatricians should be aware of and systematically search for CP in the differential diagnosis of chronic
abdominal pain
. As malnutrition is highly prevalent in CP patients, patients at nutritional risk should be identified in order to allow for dietary counseling and nutritional intervention using oral supplements. Patients should follow a healthy balanced diet taken in small meals and snacks, with normal fat content. Enzyme replacement therapy is beneficial to symptomatic patients, but also in cases of subclinical insufficiency. Regular follow-up should be considered in CP patients, primarily to detect subclinical maldigestion and the development of pancreatogenic diabetes. Screening for pancreatic cancer is not recommended in CP patients, except in those with the hereditary form.

The existence of primary lymph node (LN) gastrinoma is questionable and controversial. In fact, the presence of gastrinoma in such uncommon site raises the possibility of metastasis from another occult primary site. An extensive evaluation and careful follow-up is always warranted. A female aged 48 years presented with chronic
abdominal pain
and watery diarrhoea. Her serum gastrin and chromogranin were elevated, and an underlying gastrinoma was suspected. Further evaluation with an octreotide scan, an endoscopic ultrasound and a
secretin
stimulation test confirmed the diagnosis. Further evaluation for multiple endocrine neoplasia-1 syndrome was negative. She underwent a surgical enucleation near the head of the pancreas. No other lesions were found after careful exploration of the gastrinoma triangle. Histology showed a LN with a neuroendocrine tumour that tested positively with gastrin and chromogranin stains. Her symptoms resolved postoperatively, her serum gastrin normalised and a repeated octreotide scan was negative.

Pancreas divisum (PD) is the most common developmental anatomic variant of pancreatic duct. The attention towards the PD has grown significantly since there are reports that this condition may cause acute relapsing pancreatitis, chronic pancreatitis and chronic
abdominal pain
syndrome. Furthermore, over the years, there have been multiple reports of PD associated with different types of tumors. There is evidence that PD can be associated with pancreatic tumors (up to 12.5% of cases). The golden standard for diagnosing PD is endoscopic retrograde cholangiopancreatography, but since it is an invasive procedure magnetic resonance cholangiopancreatography with
secretin
is a good alternative. In case the patient is symptomatic, endoscopic or surgical treatment should be performed. This review describes the key points of the pathophysiology, diagnostic modalities, risks of pancreatitis and tumors, as well as treatment options of PD.
